2, a plurality of contacts 20, a metal shell 30 covering the periphery of the housing 10, and fixing means 40 for fixing the housing 10 on the circuit board 50. The housing 10 is formed by molding an insulating resin material. The housing 10 extends in the longitudinal direction and has a fitting portion 11 with a mating connector (not shown). Circuit board 50 formed at both ends in the direction
A surface mounting portion 12 (only the surface mounting portion formed at one end is shown) which is surface mounted on the upper surface. Each surface mount section 12
Is formed with a through-hole 13 through which the screw portion 42 of the mounting screw 41 constituting the fixing means 40 is inserted. In addition, a positioning post 14 protruding downward is formed on the lower surface of each surface mounting portion 12. The positioning post 14 is inserted into a through hole (not shown) formed in the circuit board 50 when mounting the electric connector 1 on the circuit board 50, and positions the electric connector 1. The plurality of contacts 20 are connected to the housing 10.
Are attached in two rows along the longitudinal direction of the fitting portion 11. Each contact 20 is formed by punching and bending a metal plate.
And a contact pad 21 that contacts the mating contact of the mating connector, and extends from the contact section 21 to the outside of the fitting section 11 and is bent downward to be conductive pads (not shown) on the circuit board 50. 2) Solder connection part 2 to be soldered to
And 2. The lower surface of all solder connection parts 22
The coplanarity (flatness) is maintained on the same surface as the lower surface of the surface mounting portion 12 of the housing 10 surface mounted on the circuit board 50. The metal shell 30 is formed by punching and bending a metal plate. The upper shell surface 31 covering the upper wall of the fitting portion 11 of the housing 10 and the side walls of the fitting portion 11 are formed. Side plate surface 32 to cover, lower plate surface 33 to cover the lower wall of fitting portion 11, and rear plate surface 34 to cover the rear wall of fitting portion 11
have. Each side plate surface 32 has an elastic tongue piece 35 extending along the upper surface of the surface mounting portion 12 of the housing 10 and extending beside the through hole 13 formed in the surface mounting portion 12.
Are formed integrally with the side plate surface 32. Each elastic tongue piece 35 includes an extending portion 35a extending from the side plate surface 32 along the upper surface of the surface mounting portion 12, an inclined piece portion 35b extending obliquely upward from the extending portion 35a, and a surface mounting portion from the inclined piece portion 35b. The parallel piece 35c extends substantially parallel to the upper surface of the base 12 at a predetermined interval, and extends outward from the surface mounting part 12.
And a hanging piece 35d bent downward from the parallel piece 35c, and a contact piece 35e bent inward toward the surface mount 12 from the lower end of the hanging piece 35d. The hanging piece 35 d is the surface mounting portion 1 of the housing 10.
2 is slightly inclined with respect to a direction orthogonal to the lower surface. Before the electric connector 1 is attached to the circuit board 50, the lower end of the contact piece 35e is connected to the solder connecting portion 2 of the contact 20.
2, that is, a height H above the lower surface of the surface mounting portion 12 of the housing 10. In addition, on the side plate surface 32 of the metal shell 30, a protection piece 37 having a substantially U-shaped cross section adjacent to the elastic tongue piece 35 and the slit 36 is integrally formed. The protective piece 37 has a function of protecting the elastic tongue piece 35 from being deformed by an external factor before attaching the metal shell 30 to the housing 10. As shown in FIG. 3, the fixing means 40 includes a through hole 13 of the surface mounting portion 12 and a through hole 51 of the circuit board 50.
And a nut (not shown) that is screwed into the screw portion 42 of the mounting screw 41 from below the circuit board 50 from below. Next, a method of fixing the electric connector 1 on the circuit board 50 will be described.
Is mounted on the circuit board 50, and the solder connection portions 22 of all the contacts 20 are connected by soldering to the conductive pads on the circuit board 50. At this time, as shown in FIG. 2, the lower end of the contact piece 35e is floating above the lower surface of the solder connection portion 22 of the contact 20, so that the elastic tongue 35 contacts the surface of the circuit board 50. By doing so, the solder connection portion 22 does not rise from the surface of the circuit board 50. Therefore, the solder connection part 22 is appropriately connected to the conductive pad on the circuit board 50 by soldering. Next, as shown in FIG. 3, the screw portion 42 of the mounting screw 41 is inserted into the through hole 13 of the housing 10 and the through hole 51 of the circuit board 50, and a nut is inserted from below the circuit board 50 into the screw portion 42 of the mounting screw 41. And screwed in. Thus, the electrical connector 1 is fixed on the circuit board 50. At this time, the lower surface of the head 43 of the mounting screw 41 is the upper surface of the parallel piece 35c of the elastic tongue piece 35, the inclined piece 3
By contacting the upper surface of 5b and the upper surface of extension 35a in this order, the hanging piece 35d and the contact 35e are pressed downward, and the lower end of the contact 35e contacts the conductive pad on the circuit board 50. Thus, the metal shell 30 is grounded to the circuit board 50. As described above, according to the present invention, in order to ground the metal shell 30 to the circuit board 50, the mounting screws 41 are used.
Since no parts are required other than the fixing means 40 including the nut and the nut, the number of parts required for grounding is small, the parts can be easily managed, and the number of contacts is small and the reliability of grounding is high. When the lower end of the contact portion 35e contacts the conductive pad on the circuit board 50, the hanging piece 35d is slightly inclined with respect to the direction orthogonal to the lower surface of the surface mounting portion 12 of the housing 10. 35d is rotated toward the surface mounting portion 12 of the housing 10, and the contact portion 35d is rotated.
e slides on the conductive pad toward the surface mounting portion 12 of the housing 10. Therefore, the conductive pads on the circuit board 50 are wiped by the contact portions 35e. In addition, since the inclined surface 12a for escaping the hanging piece 35d and the notch 12b for escaping the contacting part 35e are formed on the side of the surface mounting part 12 of the housing 10, the hanging piece 35d rotates. However, the contact portion 35e does not contact the side portion of the surface mount portion 12 even if the contact portion 35e moves. According to the electrical connector according to the first aspect,
Since the metal shell integrally has an elastic tongue piece extending downward from a part of the metal shell and having a lower end floating above the lower surface of the solder connection part of the contact, the electric connector is mounted on the circuit board. When the solder connection portion is connected by soldering, the elastic tongue for grounding the metal shell to the circuit board comes into contact with the surface of the circuit board, so that the solder connection portion does not rise from the surface of the circuit board. For this reason, the solder connection portion is appropriately solder-connected to the conductive pad on the circuit board. Also, the elastic tongue is pressed downward by the fixing means when the housing is fixed on the circuit board by the fixing means so that the lower end comes into contact with the circuit board. Since no parts other than the fixing means are required for grounding the circuit board, the number of parts required for grounding is small, the management of parts is easy, and the number of contacts is small and the reliability of grounding is high. .
